Overview of PETG and PCTG

PETG and PCTG are two popular resins on the market, both offering excellent clarity, durability and performance. However, there are some differences in application areas.

What is PETG?

PETG is a thermoplastic polyester. PETG is an adaptation of PET where the ‘G’ stands for glycol such as CHDM or NPG, which is added at a molecular level to offer different chemical and optical properties.

Key Features of PETG

• Transparency: PETG offers excellent transparency, suitable for transparent packaging and display products.
• Impact Resistance: PETG is highly impact resistant, ensuring that the product can withstand daily wear and tear.
• Thermoformability: PETG is easy to process and thermoform and is capable of producing complex designs and shapes.
• Recyclability: PETG is recyclable.

Applications of PETG

PETG has applications in a range of industries due to being resistant to heat, impact and solvents. It is widely used for food/drink containers, cosmetic packaging, film/sheet applications such as ID cards, advertising displays, and shrinkable films.

What is PCTG?

Adding more CHDM into the molecular chain, typically more than 40%, we can get PCTG.

Key Features of PCTG

• High Durability: PCTG is stronger than PETG, offering enhanced crack resistance and impact resistance, maintaining stability even under harsh conditions.
• Chemical Resistance: PCTG performs excellently when exposed to chemicals and harsh environments.
• Transparency and Appearance: Like PETG, PCTG also provides outstanding transparency.
• Heat Resistance: PCTG has better heat resistance than PETG, making it suitable for high-temperature applications.

Applications of PCTG

PCTG has better physical and chemical properties than PETG. It’s an ideal candidate for water/milk bottles, small home appliances, e-cigarettes, medical devices, etc.

How to Choose Between PETG and PCTG for Your Business

• Application needs: If you need a resin with high clarity and impact resistance for general packaging or consumer products, PETG is a good choice. If your application involves chemicals or high temperatures, PCTG may be more appropriate.
• Cost-effectiveness: Although PETG is generally less expensive than PCTG, PCTG is more cost-effective in some specialty applications due to its higher durability and chemical resistance.
• Processing needs: Both resins are easy to process, but PETG is easier to thermoform than PCTG due to its lower melting point.
